Special Attacks
In addition to the thirty-two pieces on the board, Cosplay Chess also has special attacks whereby one character calls on another from back stage to help in combat. Examples of special attacks in use: Sakura (Cardcaptor Sakura) summoning Kero-chan, or Naruto (Naruto) doing Kage-Bunshin no Jitsu and having other Narutos rush on stage. If you have a character whom you think would make a good special attack or if you have a second person willing to cosplay as an appropriate character for your special attack, you can apply as a special attack by writing to our Cosplay Chess Director.
Also, remember that you’ll need an attack scene and a death scene. An example of a death scene would be Cloud picking up Aeris’ body after she died. Try to plan at least one of each. You’ll be contacted by the Cosplay Chess Director to discuss your plans.

You don't have to worry about the french, some players only talk english, some only french, and some both, we always have both languages used at the meetup before the game, and the game is pretty much billingual as well ^^

It is FINALLY Open! The website was bypass and the info is on the Otakuthon forum, I have copy paste the main info on the first post, but the ansers/replies part shall be next to this post (sorry, too big for coscom apparently).

@FallenWingsHeal: You can always send an image of an AlBhed, and and image of a Steampunk costume, and say it's a mixt of both ^^

@Shouri no Hana: I think it would be fine, but to be sure just send a pic of normal Fang, and a pic of a dragoon (you can always go with Kain even though it won't be the same, but it still gives an idea), and say it's Fang dragoon style, lol.

I'll send a post on the official thread asking if it's ok just to be sure, and I can also send a PM to Kat in case you don't have a Otakuthon forum account ^^

@Nefer: I did send off an application e-mail detailing that it was Fang dressed in traditional dragoon armor under the context of Dark Dragoon, for the life of me I didn't think to include an image of Fang herself.

I can just resend my form, I'm seeing the artist who's doing up my Dragoon Fang tomorrow, but I know I won't be getting it done tomorrow. Argh, I messed up.

Well, I think it will be fine, but ya, if you want to be sure you can always resend another application, or well, just foward your own email to them again and add at the beginning that you forgot to add a pic of Fang herself, and just renote that it's Dark Dragoon Fang, therefore not exactly the same picture BUT the same character anyway... Though don't worry, you didn't mess up, lol, and I'm sure Amoe (one of the player) will understand your character, as for Mao-chan (the other player) I'm sure she will too as she did cosplay from FF13 before too ^^
